This Current Report on Form 8-K/A (this Second Amendment) updates information
originally provided in a Current Report on Form 8-K, filed September 9, 2011 (the Original Filing) and a Current Report on Form 8-K/A, filed October 6, 2011 (the First Amendment). WRIT has previously reported in the
Original Filing and the First Amendment closing on the first four out of five separate purchase and sale agreements with AP AG Portfolio, LLC to effectuate the sale of WRITs entire industrial portfolio and two office properties. Except for the
following, this Second Amendment does not modify or update any other disclosure contained in the Original Filing and the First Amendment, and this Second Amendment should be read in conjunction with the Original Filing, the First Amendment and
WRITs Current Report on Form 8-K, filed August 9, 2011.

Item 2.01 Completion of Acquisition or Disposition of Assets.

On November 1, 2011, WRIT closed on the fifth and final purchase and sale agreement. The sales price under this
agreement is $70,560,324. Under the terms of an amendment to Purchase and Sale Agreement #5, this sales price includes an $875,000 increase over the original sales price because WRIT prepaid the mortgage notes secured by Dulles Business Park prior
to November 1, 2011. The $875,000 sales price increase partially offsets prepayment penalties of approximately $1.0 million.

The properties, purchase prices and actual closing dates under each of the purchase and sale agreements are as follows:
